I found an old topic about this subject, dating back to 2015.
Since there was no clear answers given I’d like to suggest it again and see what kind of response it gets this time around.
Why don’t we have an option to lock a certain role?
I feel like I spend most of my time in lobbies, trying to roll a dice to get that specific role I want to play, leaving (or someone else leaving) when one doesn’t get it, leaving anyway because then you have an AI hunter, more than 1 player leaving because you end up in a lobby with 3 players wanting to play a monster, and so on.
I honestly wouldn’t mind spending few extra minutes searching for players if I was certain to get that role I want.
